14 Claims.

The present invention relates to devices for precisely indicating ingeneral changes of or actual values, functions of machines andmaterials, and more specifically the sale prices of stocks, bonds,commodities,- etc., whereby the range as well as volume or quotations ofsuch items may be precisely observed and recorded. Hereinafter referencewill only be had to transactionsv for stocks.v but it is understood thatthe invention is equally applicable to any item or function where it isdesired to precisely observe and indicate liuctuations, volume andchanges, in any unit of time and from day to day.

It is therefore an object of the invention to provide devicesv to set upand indicate stock market quotations, such as sale prices whereby therange of one or more or groups of stocks may be continuously andprecisely indicated in cooperation, if desired, with a graph or diagram,upon receiving information of such quotations by a stock ticker, or byother means, so that at any time during a market session the device willindicate the previous sessions close or the opening price or sale aswell as the high and low sales er prices. In this manner' it is possibleto follow the trend or range, that' is, activity, of the market as thesessionA progresses which will also be an indication of the support ornon-support of the particular issue or issues of the market.

A still further object of this invention is to provide manual means for'precisely indicating by graph or diagram continuously from day to daythe price of' one or more stocks so that the trend or movement, of theprices may be ascertained and compared as the market is in session andwherein means is provided for enabling the price at a given time of oneor more stocks to be instantly observed and such price or pricescompared with previous high and low prices.

A further object' of this invention is to provide a machine forgraphically indicating stock quotations wherein means or an indicatingdevice is provided, preferably in' the form of a scale representing.fractional stock quotations and4 an indicator,. for precisely andsuccessively displaying cr indicating the various price quotations of`a, stock and in which means is provided for operating the indicatingdevice so as to display successive prices in the stock and at the sametime for operating a graphical indicating mechanism to assist in forminga record or diagram embodying each change in price.

Further' objects will be apparent from the. following description takenin connection with the accompanying drawings showing various embodimentsof the invention and in which:

Fig. 6 is a cross section taken on line 6 3 of Fig. 1 in the directionor the arrows, and

Fig. 7 is a plan view of a portion of the graph paper sheet.

The indicator is of. the type which is manually operable. The instrumenthas all of its parts mounted on a vbase plate 33 having a spring-pressedfastening pin 3| at each end thereofl to fasten the instrument on aboard or other supportA where desired. The base plate 33 is provided atone side, Fig. l, with a pair of spaced integral guide tracks 32extending 1ongitudinally along the plate and parallel to each other witha toothed rack 33 intermediate and parallel to the tracks; These tracks32 have on oneV side a groove 34, Figs. 5 and 6, which acts as a guidefor the indicating or marking sliders 35 and 36, of which there are twoin number, and each slider extends over both tracks 32 bridging theintervening space including the rack 33 andV is provided with anactuating knob 49. Also each slider has opposed laterally extendingtongues- 31, Fig. 6, which extends into the grooves 34 so that while thesliders can move easily they will not change their position or drop ifthe instrument is held or mounted. in a vertical position. -Each sliderhas a pair of oppositely extending pointed or marking edges 38 and 39,the purpose of which will be explained.

An intermediate slider or indicator 43, also slides and moves on theguide tracks 32 and has inwardly directed tongues 31 contacting in andsliding in the grooves 34. The indicator 43 also .has side plates 4l,Fig. 6, which tend to contact the internal sides of the tracks 32opposite the sides in which the grooves 34 are provided. The plates 4las well as the main Apartsv or frame of the slider it) are provided withvertically elongated :slots 42, Figs. 2 and 5, in which a shaft 43 of anactuating roller 44 is rotatably mounted. The actuating roller 44!y hasa pair of spaced peripherially knurled or milled disks 45 between whicha gear 43 is provided and interconnects said disks 45, the shaft 43,disks 45 and gear 46 being preferably made integral. As shown in Fig. 6the gear 46 meshes with the rack 33 so that by actuating the knurlededges of the disks 45 by a nger of the operator the slider will travelalong the tracks 32. The slider 40 is also provided with a pair ofoppositely directed pointers 41 and 48 in the form of sharp pins whichare suitably secured to the frame of the slider for the purpose whichwill be explained.

The indicating instrument is provided with a pair of scales 50 and 5|,Figs, 1 and 6, provided in suitable grooves for this purpose in the baseplate. The scale 50 is intended to be fixed, for the purpose which willbe explained, but the scale is movable and adjustable, which for thelatter purpose the scale, in the form of a band, travels in the groove52, Fig. 6, in the base plate 3|) having overlapping sides 53 along thelongitudinal edges thereof and is provided with reels or spools 54, Fig.2, on which the ends of the band are fastened and wound. Each reel 54 oneach end of the plate 39, is rotatably mounted in brackets 55 withfrictional contact on the adjacent sides and these brackets are suitablysecured on .the plate by means of screws 58, Fig. 1. Also each reel 54is provided with a manual actuating knob or Wheel 51 and an idler roller58 each of which is rotatably mounted in a bracket 55 to maintain theband down in the bottom'of the groove 52. Y

Upon turning either knob 51 lthe band '5| may be adjusted, that is byturning the left hand knob 51, Fig. 1, clockwise or the right hand knobcounter-clockwise each time winding the band or tape 5| on its drivingreel in the desired direcu tion and pulling it from the other reel forthe purpose which will be explained.

A pair of abutments 59, Figs. 1 and 5, are pro vided in the base plate30, one on each side end thereof for the purpose of protecting thepointed ends of the pointers 41 and 38 so that if the instrument isplaced or accidentally falls on its longitudinal edge on the sideadjacent the fastening pins 3l the rather sharp points will not bedamaged. Also as seen in Figs. 2 and 5 the marking edge 60 of eachpointer 38 and 39 is concave along its longitudinal edge so that thesliders and 36 when brought together against the indicator 40, the endpoints of the pointers 38 and 41, and 39 and 48, respectively, will allpoint and indicate as near as possible to a single point or mark.

Each fastening pin 3| is in the form of a push pin 6| mounted in acylinder 62 secured on each end on the base plate 30. enlarged portion63 which abu-ts against the top end of the cylindeil 82 and the pin isprovided with a spring 64 and a head portion 65. When the instrument isplaced on a board or other support it is securely held in place bypushing down the -pins 6 I, but by pulling up on the head portions B5the instrument is released. As a safety measure, it is desirable .toprovide an auxiliary pin 68, Fig. 1, fastened to one of the pins 3| bymeans of a chain 61 whereby upon inadvertent release of the pins 3| theinstrument will not fall to the floor assuming that the lnstrument isused on a board arranged at a slight angle from the vertical.

The instrument operates as follows, assuming that it is used inconnection with a single days transactions for a particular stock and isused in cooperation with a graph paper; the latter being mounted on aboard.

The instrument is iirst adjusted by setting the Each pin 6I has anpointers 41 and 43, of the slide 40, in the central position so that thepointer 48 will register with the "0 mark B8, Fig. 1, on the permanentscale 59. The slides 35 and 36 are then brought against the center slide40 so that pointers 38 and 41 as well as 39 and 48 will be adjacent toeach other. The instrument is then so placed on the graph paper 69, Fig.'7, to underlie'the left edge of the structure of Fig. 6; on which everyvertical line 10 represents the extreme range, high and low prices of aparticular days transactions, and the horizontal lines 1| represent theclosing price for the particular day represented by the left handvertical line; by placing pointers 38 and 41 on the closing price line12, the longitudinal axis of the instrument being parallel with thelines 1l). The instrument is then fastened down by pushing the pins 6|into a board and placing the auxiliary pin 6B in the board above theinstrument as a safeguard. The next step is to adjust the movable band5| so that pointers 48 and 39 will indicate the exact closing price, onthe band 5|, of the previous day, as represented by the line 12.

The instrumen-t is now ready for use and as an example, it might beassumed that the pointer 48 is set at 35 which represents the previousdays closing price. The rst sale price may be 36 which is indicated bymoving the center slide 40 to the right, Fig. 1, by rotating the disks45 and therewith the gear 46 which, due to the toothed rack 33, willmove the slide 40 which is manually stopped when the pointer 48registers with the 36 line of the scale 5|. Thisl movement of the slide40 will move before it the slide 35 to the right so that its pointer 39will also point to the 35 line on scale 5 I.

The next transaction is similarly recorded by moving the slide 40 eitherto the right or left, Fig. 1, depending upon whether the succeedingtransactions are higher or lower than the preceding transactions. It isobvious that the pointers 39 and 48 as Well as 38 and 41 will indicatethe range, high and low, as well as the last transaction at any time,and it can be momentarily observed as to the high and low range and lasttransaction of that day whereas the pointers 38 and 41 will indicate thesame information, but it can be observed in relation to the previous dayor days .transactions and said pointers are thus preparing the necessaryinformation to be placed 0n the permanent record, sheet 69, after thelast transaction of the day has been completed. It can, for example, beassumed that the slides 35, 35 and 4i! are in the position indicated inFig. 1 at the close of the days transactions in which pointers 38 and 39indicate the high and low prices as a range with the pointers 41 and 48indicating the closing price. A vertical line 10 is now dra-wn on thegraph paper 69 to indicate the range for the day and a short horizontalline 1| to indicate the last or closing price transaction. It is, ofcourse, obvious that the pointers 33 and 41, or merely 41, can beprovided with or may constitute an inking or marking pen so that thepermanent line 10 may be applied or drawn on the sheet 83 as thetransactions are carried out. The edges 38 may be used as straightedges, if desired, to mark the horizontal lines 1| on the graph paper69.

The purpose of the slot 42 for the shaft 43 is to permit the disks 45and gear 4B to be raised so that the latter will not mesh with the rack33 to move the slider 40 quickly without any rotary action.
